Combination method mounting technique for ultra-large type steel converter

Abstract

The invention relates to a combination method installation technology for an ultra large steel-smelting converter, belonging to the installation of steel-smelting devices, which is characterized in that respectively installing hydraulic presses and cylindrical safety cushion blocks on the upper portions of four vertical props of a supporting platform relatively to the chassis portions of bearing bases on the driving side and non driving side of the converter, installing pad beams which are respectively indentified with height marks of the chassis of the bearing bases and are integrated together on steel pillars or steel beams of the operational platform on the front of the converter, assembling three components of the converter on charging bays, suspending the three components on the hydraulic presses on the supporting platform and the pad beams which are provided with rolling rods and assembling integrally, regulating the hydraulic presses to make each supporting point with balance force, installing a winding engine and a main pulley block on the advancing end of a ladle car to drag the ladle car and the supporting platform, arranging a single-sheaved block on the driving lateral bearing base which is dragged by a line hook of a steel-melting bay, correcting directions by regulating the rolling rods, and slowly dragging the whole converter to the installation position of the steel-melting bay, which is safe and reliable, and has high effect and strong operability.

Description

technical field [0001] The invention belongs to the installation of steel making equipment, in particular to the installation of a large or super large steel making converter. Background technique [0002] Due to the large size and heavy weight of large or super-large steel-making converters, which can weigh hundreds of tons or even nearly 1,000 tons after assembly, they cannot be directly hoisted in place by cranes on the steel-making span. Adopt "slip method" or "trolley method" for installation; slip method: when assembling, in the charging span, use the large bridge crane of the charging span to assemble the three major parts of the converter body: the support ring and the bearing seat, the furnace shell and the converter The transmission device is assembled into a whole, and then the whole is slid to the installation position of the steel-making span. In the stainless steel-making project of Shanghai Baosteel, the converter is installed by the sliding method, but the st...

Problems solved by technology

[0002] Due to the large size and heavy weight of large or super-large steelmaking converters, which can weigh hundreds of tons or even nearly a thousand tons after assembly, the steelmaking span cannot be directly hoisted in place by crane. At present, the installation of large or super large steelmaking converters at home and abroad is generally Use the "slip method" or "trolley method" for installation; slip method: when assembling, use a large bridge crane on the feeding span to move the three major parts of the converter body: the support ring and the bearing seat, the furnace shell and the converter The transmission device is assembled into a whole, and then the whole slides to the installation position of the steelmaking span. The converter is installed by the sliding method in the Shanghai Baosteel stainless steel steelmaking project, but the steel column foundation, steel columns and steel beams of the operating platform in front of the furnace must be To increase the design load, the design of the bearing base must be changed, increasing the project investment, and there are safety risks. Therefore, the installation of large or super-large steelmaking converters by sliding method requires large project investment and safety risks; The installation of steel converters generally adopts the ladle trolley method, that is, a supporting platform is set up on the ladle trolley, but only the two major parts of the assembled converter body: the support ring, the bearing seat and the furnace shell can be moved to the installation position as a whole. The stability is poor when moving, and the transmission device of the steelmaking converter cannot be installed in place at the same time
